3 Claims. (Cl. 112114) My invention relates to improvements in workholders for sewing machines, whereby a closure securing device, such asa hook and eye, may be held in definite space relationship to the stitchforming machine. The stitch forming machine used with the device,hereinafter described, is of the type generally used to secure buttons,hooks, or other fasteners to fabrics or pliable materials.

It is an object of my invention to construct a positioning and retainingdevice that will securely and definitely position a closure securingdevice in definite space relationship to the stitch forming machine.

Another object of my invention is to construct a positioning andretaining device that will securely and definitely position a closuresecuring device in such a way as to require no efiort on the part of theoperator, either by hand or hand held tools, during the application ofthe closure securing device.

Another object of my invention is to construct a positioning andretaining device that will readily position and secure the componentmembers of the closure securing device without requiring any mechanicalchange to the positioning and securing features of the device.

Another object of my invention is to construct a closure securing andpositioning device that will remain relatively free from theaccumulation of oil impregnated lint or dirt which would impair theoperation of the device or ultimately render the device temporarilyinoperative.

Another object of my invention is to construct a closure securing,positioning and retaining holder that can be readily positioned underthe needle of the stitch forming machine by the operator.

Another object of my invention is to construct a closure securing andpositioning device of the character described which is easily andeconomically produced, which is sturdy and compact in construction,which provides the maximum protection to the operator, and whose userequires the minimum of effort on the part of the operator.

With the above and related objects in view, my invention consists indetails of construction as hereinafter shall be described, thedescription will be more readily understood when the description is readin conjunction with the accompanying drawings in which:

Fig. 1 is an isometric view of the closure securing, positioning andretaining device embodying my invention.

Fig. 2 is an isometric view of the retaining member of the closuresecuring, positioning and retaining device.

Fig. 3 is an isometric view of the positioning member of the closuresecuring, positioning and retaining device.

Fig. 4 is a partial sectional elevational view showing the male portionof a closure securing device in position in the closure securing,positioning and retaining device.

Fig. 5 is a partial sectional elevational view showing the femaleportion of a closure securing device in position in the closure securingpositioning and retaining device.

Fig. 6 is a plan elevational view showing the positioning member of theclosure securing, positioning and retaining Patented Apr. 16, 1957 "icedevice (securing member not shown) showing the male portion of theclosure securing device in position.

Fig. 7 is a plan elevational view showing the positioning member of theclosure securing, positioning and retaining device (securing member notshown) showing the female portion of the closure securing device inposition.

The closure securing, positioning and retaining device shown on theaccompanying drawings is constructed to be secured to standard stitchforming machines. The only portion of said stitch forming machine shownon these drawings is the needle N shown in Fig. 4 and Fig. 5.

Fig. 8 is an isometric view showing a modification of the supporting andpositioning members of the closure securing, positioning and retainingholder. This modification provides for lateral and transverse adjustmentof the positioning member of the closure securing, positioning andretaining device.

Referring now in greater detail to the drawings, I disclose a closuresecuring, positioning and retaining device comprising a positioningmember A; the positioning member being pierced with hole 1 that arearranged to receive securing means, not shown, so that the device can besecurely attached to a standard stitch forming machine.

The outer or work end of the positioning member A has a definitelyshaped cavity 2 therein, said cavity having two opposed curved surfaces3 with inwardly projecting flanges 4 arranged to receive the loopportions 5 and 6, of the male C and female D closure securing devices;said flanges 4 have a circular inner edge 7 arranged so that it is clearof the needle of and the stitches formed by the stitch forming machine.

An eye receiving receptacle 8, part of cavity 2, square in form, isarranged to receive the eye 9 of the female closure securing device D, ahook receiving receptacle 10, an extension of and part of the cavity 2,is arranged to receive the hook 11 of the male closure securing device;said hook receiving receptacle 10 extends completely through thepositioning member and serves as a discharge outlet for lint or dirtthat may accumulate in the cavity 2.

The features of the cavity 2 in the support and positioning member A, asabove described, are arranged for definitely positioning both the male Cand female D closure securing devices in the work end of the closuresecuring positioning and retaining device.

The closure securing devices C and D are held in position in the closuresecuring positioning and retaining device by the retaining member B;said retaining member is definitely positioned and the positioningmember A by the pin 12, which interfits with the hole 19 in theretaining member B, the yoke 13, and the downwardly extending ribs 14 atthe work end of the retaining member, said ribs interfitting with thesides 15 of the eye receiving receptacle 8 of the cavity 2 in thepositioning member A. A spring 16, retained by the yoke 13 and apositioning screw 17, maintains pressure on the retaining member B.

The Work end of the closure securing retaining member B also has twodownwardly extending ribs 14, said ribs interfit with the eye receivingreceptacle 8 of the cavity 2 and are of such a length in the downwarddirection that they engage the eye of the female closure device D whenthe female closure device is in position in the positioning member A,the retaining member B is forced upward by this engagement of the ribs14 and the eye 9 of the female closure securing device D, thisarrangement provides the tension necessary to retain the closuresecuring device D in position in the positioning member A.

In Fig. 8 I have illustrated a modification to the support andpositioning means of my closure securing positioning and retainingdevice. In the modification illustrated, the positioning member A1 isarranged to c0opa V 3 1 erat'e with a lateral and transverse adjustmentmember 21, said positioning *member A1 is rotatably "attached to 'saidadjustment member 21 by the bolt 27, transverse adjustment is madepossible by movement of thetsecuring bolt 28in the elongated "hole 29infthe'adjustm'etit member-21. The adjustment member is atteicliedtothebracket member Z'T bythe bolts 25;h'ow'ever, {lateral movement of the Vadjustmentrnember is 'provibledbythe longation'ofithe 4 able detail,such description is intended as illustrative rather than limiting, asthe invention may 'be variously embodied and the scope is to bedetermined as claimed.
